My money is on a bug in Outlook and how it handles IMAP and RR. See
http://www.slipstick.com/problems/rr_ndr.asp for an explanation of the bug.
While outlook can be configured to not return RR, accessing the message from
multiple computers is causing problems.
It's all gmail accounts? I would see if a rule in Gmail can mark messages
read as the message arrives. This should eliminate multiple RR if the
problem is the RR/IMAP bug.
Being someone who doesn't like unnecessary RR's, I would copy his messages
before reading - mark one read, delete one copy, mark one read etc... just
to annoy him. (Yes, I've done it before.

)
Does your friend use outlook? if so, he could create a rule to request RR
and make an exception for your addresses.
